And I don't think anyone would complain if Iran wants to sanction the US

So you think that makes it okay for Iran to do it? Hypocrisy doesn't make someone else's bad actions acceptable.

This is why those discussions from a morally neutral standpoint are a waste of time. It’s entirely reasonable for one side to punish the others for having nukes while having those itself. We are not some impartial aliens surveying the planet, each of us is affected by these things.
